I installed the amp on a polaris rzr, pushing a 10" sup and 2 6" mids, it sounds great and the best part is when it gets muddy i just spray it of. I'm not a stereo man but due to the sound and especialy the durability i would highly reccomend.

August 10, 2011 Tower Speaker Amp

Bernie from Omaha, Nebraska

I installed this amp for my 6.5" polk tower speakers. I was a little worried that I'd have to run it in the bridged mode to get enough power to hear while wakeboarding but they rock even at 60 feet behind the boat going 20 MPH. I plan to use the rear channel for a subwoofer now that I know I only need the front channel for the tower speakers. I can't say much about durability but so far so good. FYI I installed a subwoofer volume control in the RCA cables to the amp which comes in real handy for cranking up the tower speakers or turning them down to match the in boat speakers when cruising.

I would recommend this Amp to someone interested in a nice "kick" to their current stereo set up. I use this JBL with a Sony Marine CDX M60ui for the perfect combination of power and clarity. The JBL Amp works perfect to supply excellent power whether you are listening while you are in the boat or if you need a little extra power because you are outside the boat or a short distance away. This unit rocks the docks and shakes the lakes.
